Polyvinyl chloride commonly abbreviated PVC is the third-most widely produced plastic after polyethylene and propylene.PVC is produced by polymerization of the monomer vinyl chloride (VCM) - PVC grades produced by NPC with their general information ,applications , and specifications are as follow:
Calendering: This grade processed without plasticizer is used for calendering ,for
example HT-film can be produced by this grade. It processed with plasticizer
is used as additive polymer in compounds for calendering ,for example film
and floor covering can be produced.
Injection molding :such as building parts ,water fittings
,WC flush tanks, electrical switch cabinets etc.
Extrusion: Pipe and profile
:This grade in compounds permits a trouble free processing on conventional
PVC injection molding machines for sanitary ware ,building parts ,water
fitting ,WC flush tanks etc .
Extrusion of flexible sections and hoses: This grade
processed with plasticizer is particularly suitable for the manufacture of
flexible sections & hoses. The most varied field of applications are
satisfied by this product like ,transparent and solid colored hoses and
sections, refrigerator seals , sealing for window & doors , film
&sheets. Grade S7054 processed with plasticizer is suitable for wide
range of thickness like film and floor covering.
Injection molding : This grade in compounds permits a
trouble free processing on conventional PVC injection molding machines for
camping / leisure equipment ,packaging ,roof lights ,electronic /phone
equipment etc. this grades processed with plasticizer is used for the
Cable industry: this grade processed with plasticizer is
widely used for the manufacture of cable insulation and sheathing for
voltages up to 20KV.It is most suitable for the manufacture of high quality
